Answer:  The given statement is true.

Explanation:

Incineration: It is a technique in which organic substance present in waste material is burned down to break them into its components.

For: Example : Burning of powder of wooden chips gives carbon dioxide gas ,nitrogen-dioxide in small amounts and heat energy.

Although incineration can break down harmful chemicals but the by-product formed are hazardous because:

  • Oxides of nitrogen and sulfurs are also released which pollutes the air and becomes the main cause for acid rains.
  • Green house gases are produced which disturbs the balance of atmosphere and climate.
  • Increases air pollution by which it becomes unfit to breathe in.
  • Also pollutes soil.

Hence, the given statement is true.

Calculate the moles and grams of solute in 2.0 L of 0.30M Na SO..
Ostrovityanka [42]

Answer:

Number of moles of solute = 0.6 mole

Mass =13.8 g

Explanation:

Given data:

Number of moles of sodium = ?

Volume = 2.0 L

Molarity = 0.30 M

Mass in gram of sodium= ?

Solution:

<em>Number of moles:</em>

Molarity = number of moles of solute / volume in litter

Number of moles of solute = Molarity × volume in litter

Number of moles of solute = 0.30 M × 2.0 L

Number of moles of solute = 0.6 mole

<em>Mass in gram:</em>

Mass = Number of moles × molar mass

Mass = 0.6 mole× 23 g/mol

Mass =13.8 g
